What are ecosystems

1. WHAT ARE ECOSYSTEMS?

2. Where Things Live

Living things need a place to live and
grow.

3. Fish live in water.

4. Birds live in trees and fly through the air.

5. Plants grow where there is soil, water and sun.

6. Main Idea and Details

Living things need
a place to live
and grow.
Fish live in water.
Birds live in trees
and fly in the air.
Plants grow where
there is soil, water
and sun.

7. ENVIRONMENT

The living and
nonliving things that
surround a living
thing make up its
environment.

8. What do living things get from their environments?

Many living things share their
environments and its resources.
Food
Water
Oxygen
Space

9. Parts of an Ecosystem

An ecosystem is made up of all the living
and nonliving things in an environment.

10. Different types of organisms live in an ecosystem.

A group of organisms
of the same kind
living in the same
place is a
population.

11. All the population that live in an ecosystem at the same time form a community.

12. All members of a community live in the same ecosystem but they do not all live in the same part of the ecosystem.

13. Where Plants and Animals Live

Habitat is a place where plants
and animals lives.

14. It is a place where they can meet their needs. Animals get food, water, and shelter from their habitat,

15. Organisms and their Habitats

Some organisms can survive only in
certain habitats.
For example, a polar could not find the
water it needs in a desert.

18. What are some types of ecosystems?

19. Types of Ecosystems

Deserts are very dry
ecosystems.
Desert plants and
animals can survive
with very little water.

20. Desert Plants

Desert plants, such as
cactus, have thick
stems that store
water.
The roots of a cactus
lie just below the soil
and spread far from
the plant.

21. Grassland Ecosystems

Grasslands are dry,
often flat areas of
land that are hot in
the summer and cold
in the winter.
They get more rain
and snow than
deserts but less that
most other
ecosystems.

22. Plants

The main plant in a
grassland ecosystem
is grass.
There are not many
bushes in the
grassland.
Trees are found only
by rivers and streams.

23. Saltwater Ecosystems

Saltwater ecosystems are oceans.
Oceans cover about three –fourths of
Earth’s surface, so there are more
saltwater ecosystems than any other.

24.

Sharks, sea turtles, corals and
octopus are all ocean animals.
So are whales and seals.

25. Freshwater Ecosystems

Rivers, ponds, lakes and
streams have fresh water.
Lakes and rivers are closely
tied. Some lakes are the
source for some rivers.
Important rivers, most often,
originate from lakes. Some
rivers end in lakes.
Since both rivers and lakes are
freshwater and flow in and out
of each other, they share
similar characteristics and
many species reside in both
habitats.

26. Forest Ecosystems

Forest are ecosystems
in which many trees
grow.

27. Tropical Rain Forest

A tropical rain forest
grows where it is hot
and wet all year long.
Animals such as
jaguars and monkeys
live there.

28. Deciduous Forest

What's A Temperate Deciduous
Forest Like?
One of the most interesting
features of the temperate
deciduous forest is its changing
seasons.
The word "deciduous" means
exactly what the leaves on these
trees do: change color in autumn,
fall off in the winter, and grow
back again in the spring. This
adaptation helps trees in the forest
survive winter.

29. Drawing Conclusions

Suppose all the plants in one ecosystem
died.
What do you think would happen to that
ecosystem?
Why?

What I look like
Hot and dry
Rains every day and has many trees
and plants
Enough rain for trees to grow. They
lose their leaves in the fall.
Made up of rivers, ponds, lakes and
streams and my water does not have
much salt
